Trinasolar’s Vertex N Shield Module Demonstrates Superior Reliability, Efficiency, and Cost Savings at pv magazine USA Week 2025

Trinasolar, a global leader in smart solar products and energy solutions, participated in pv magazine USA Week 2025, joining industry peers to discuss the latest developments in photovoltaic technology. On the opening day, Ethan Ely, Product Manager at Trinasolar US, delivered a presentation titled “Conquering the Elements: Bankable Shield Module Technology.”

Ely’s session focused on how Trinasolar’s Vertex N Shield module enhances the resilience and bankability of PV projects exposed to extreme environmental conditions. The module delivers a power output of 620W, achieves 23% efficiency, maintains an annual degradation rate of just 0.4%, and comes with a 30-year warranty. Its robust mechanical design meets stringent loading requirements, offering strong resistance to hail, wind, snow, and fire—all while reducing system costs.

These features make the Vertex N Shield a highly reliable and financially attractive choice for developers and investors. Supported by Trinasolar’s BloombergNEF Tier 1 manufacturer status, the module’s durability and long-term performance record strengthen project confidence and maximize returns.

Built with 2.5/2.5mm fully tempered glass, the Vertex N Shield withstands hailstones up to 55mm without tracker stowing and up to 75mm at a 45-degree stow angle, substantially reducing potential hail-related losses. Its uneven snow load capacity of 6,600 Pa demonstrates exceptional durability in real-world conditions, equivalent to sustaining up to 7.2 feet of uneven snow in a fixed-tilt position.

The module also achieves high wind load capacities of +8,000 Pa and -6,000 Pa for fixed-tilt systems, and +3,600 Pa and -3,000 Pa for tracker-mounted installations. This superior strength supports the use of shorter purlins and lowers tracker costs, improving overall system economics. Additionally, the Vertex N Shield has achieved the UL 61730-2 Type 30 (Class A+A) fire rating, exceeding industry standards for fire safety.

The Vertex N Shield’s proven reliability has earned it the title of “Overall Highest Achiever” in RETC’s PV Module Index and recognition as a “Top Performer” in the Kiwa PVEL PV Module Reliability Scorecard, highlighting its consistent performance under rigorous testing conditions.

Ely presented a case study evaluating a hypothetical 100 MW, 30-degree fixed-tilt solar installation located in a hail-prone region of western Texas. The analysis showed that using the Vertex N Shield instead of standard dual-glass modules reduced potential losses by approximately 60%, resulting in savings of about $1.72 million.

The Vertex N Shield module is built on the same n-type TOPCon advanced technology platform as Trinasolar’s other Vertex N series modules, ensuring high efficiency, dependable output, and a proven path to lower levelized cost of energy (LCOE).
